Messier 68 is a globular cluster found in the east south-east of Hydra.
It is centred about 33,600 light-years away from Earth. It is orbiting our galaxy's galactic bulge with a great eccentricity of 0.5. This takes it to 100,000 light
years from the center.
It is one of the most metal-poor globular clusters, which means it has a paucity of elements other than hydrogen and helium.
